Why can a powered access point still have a slow Ethernet link?

An access point can start normally and broadcast Wi-Fi while its wired uplink runs below the expected speed. PoE delivery and Ethernet data performance are related parts of one cable path, but success in one does not prove success in the other. List the switch port, injector if present, patch leads, permanent cable and access-point port. Read the data-rate specification for the injector as well as its PoE standard. A power-compatible older accessory can still limit a newer multi-gigabit access point.

Does upgrading from U6+ to U7 Lite add 6 GHz support?

UniFi's U7 Lite and U6+ serve similar compact access-point roles, but the newer generation changes several planning requirements. The U7 Lite specification lists a 2.5 GbE uplink; the U6+ lists Gigabit Ethernet. Both cited products operate on 2.4 and 5 GHz. If the upgrade goal is specifically to add 6 GHz coverage, inspect another suitable model whose specification includes that band. Wi-Fi 7 branding alone does not answer the frequency-band question.

How do I test guest isolation at a remote mesh node?

When extending Wi-Fi to an upstairs node, garden access point or detached room, verify the guest policy from that location. A network named “Guest” can be visible without proving that the intended separation is enforced along the full path. TP-Link's Deco documentation distinguishes features and guest behavior across operating modes. A separate managed access point may instead rely on VLAN mapping and router policy. Use the documented design for the equipment actually installed.

Is a MoCA PoE filter a Power over Ethernet accessory?

In MoCA installation discussions, “PoE filter” usually means a point-of-entry filter on coax. In Ethernet product listings, PoE means Power over Ethernet. Confusing the terms can lead to buying equipment that has no role in the intended installation. A suitable MoCA point-of-entry filter helps contain the relevant signals within the intended coax network. Its frequency characteristics and placement must match the service arrangement. ScreenBeam advises contacting the internet provider because filter requirements vary.
